This comprehensive study examines the effects of various dopants on the physical and chemical properties of cadmium selenide (CdSe) nanoparticles and thin films. Through systematic analysis of experimental data from recent research, it is revealed that how dopant incorporation fundamentally alters structural, optical, magnetic and electrical characteristics of CdSe-based materials. Key findings reveal that doping concentration significantly influences band gap engineering (1.14-2.61 eV range), magnetic behavior (from diamagnetic to ferromagnetic) and morphological-structural properties. This review consolidates experimental evidence from multiple characterization techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-visible spectroscopy, photoluminescence (PL) tunneling electron microscopy (TEM) and magnetic measurements to provide details about the dopant-induced property alterations and modifications.
